Hello,
I can see that you are using one brick for the volume. To get the most of distribute volume, increase the number of bricks and see there is any improvement.
Also, glusterfs has optimization settings for oVirt env, please do gluster volume set $VOLNAME group virt . Hope this document will help you
Regards
Vinayak
